FAUCET.

Specification of Letters Patent.

Application filed November 15, 1911.

To all whom it may concern:

Be it known that I, AnoNmAM J. COLLAR, a citizen of the United States,residing at Yreka, in the county of Siskiyou and State of California,have invented new and useful Improvements in Faucets, of which thefollowing is a specification.

This invention relates to a faucet, and has as its object the productionof a faucet 1n which the use of gaskets on the valve and valve seat isobviated.

The principal object of this invention is to provide a faucet which isdurable and not liable to get out of order.

Other objects will appear in the following specification.

The invention consists of the parts and the construction and combinationof parts, as hereinafter more fully described and claimed, havingreference to the accompanying drawings, in which Figure l is a view ofthe invention in vertical section, partly in elevation. Fig. 2 is ahorizontal section on the line X-X, Fig. 1. Fig. 3 is a detail frontelevation of the faucet casing with parts broken away.

In the drawings, A represents the faucet casing and B is the spoutthereon. The casing A is designed to be screwed on the do livery pipe Cand is threaded at 2 on its lower end for that purpose. A valve seat 3is formed on the interior of the casing A below the point of connectionof the spout B; the valve seat 3 being circular in plan with its facediverging outwardly and downwardly so as to receive'a tapered orfrustoconoidal shaped valve 4, which is designed to cut offconn'nunication between the delivery pipe C and the spout B andnormallyextends into and contacts the valve seat 3 from the underside thereof.

The valve-4L is mounted on the lower end of a stem 5 which extendsthrough a gland 6 on the upper end of the casing A and has a hand-hold 7mounted on its upper end, by means of which it is turned to open andclose the faucet, as will be presently described. The stem 5 is threadedfor a portion of its length within the casing A, as

indicated at 8; this threaded portion 8 screwing into an internallythreaded sleeve 9 disposed in the casing A.

The sleeve 9 is provided with diametrically o posed vertical ribs 10 10,which are adapte to extend into grooves 11--11 formed between parallelvertical ribs 12-42 on the Patented Oct. 8, 1912.

Serial No. 660,331.

interior of the casing A. The engagement of the ribs 10 on the sleeve 9by the ribs 12 on the casing A prevent the former from rotating so thatwhen the stem 5 is revolved, it will travel longitudinally. within thesleeve 9. The sleeve 9 is designed to have a vertical movement withinthe casing A and is normally retained'in its uppermost position by meansof a helical spring 13 which surrounds the stem 5 and bears between ashoulder 14 on the inner face of the casing A and the lower end of thesleeve 9.

A loose ring 15 is disposed on the stem 5 adjacent the upper end of thesleeve 9, and a similar ring 16 surrounds the stem 5 a short distanceabove the ring 15; the ring 16 resting on the end of the casing A. Apacking 17 of any suitable material is placed around the stem 5 in thespace between the rings 15 and 16, inclosed by the casing A,

and a packing ring 18 is disposed between the ring 16 and the gland 6;the packing rings 17 and 18 preventing the passage of liquids around thestem 5.

In opening the faucet the stem 5 is turned in such direction as to causeit to move down ward in the sleeve 9 and thereby unseat the valve 4 toallow fluid to pass from the de livery pipe C out the spout B. Inclosing the faucet the stem 5 is turned in the direction opposite thatrequired in opening, which causes the valve 4 to move upwardly into thevalve seat; the sleeve 9 moving downwardly a short distance inopposition to the spring 13 the moment the valve is seated, therebycushioning the closing of the valve.

The pressure of the liquid in the delivery pipe being against the lowerside of the valve 4, tends to retain it tightly seated; upward pressurebeing confined to the valve 4 and stem 5, and not transmitted to thevalve casing except through the seat 3 by reason of the sleeve 9beingslidable vertically in relation to the faucet casing. The flow of watermay be regulated when the valve 4 is wide open by bringing it close to,or in contact with, the end of the pipe C. As the threaded sleeve or nut9 is movable up and downin its case A, it will be manifest that thevalve 4- may be opened either by screwing the threaded stem through thethreaded sleeve, or by pressure upon the head 7'. The spring acts toclose the valve 4 when opened by direct pressure. The ring or washer 15approximately fitsthe case, but the central hole through which the stempasses is large enough to allow water to follow'slowly when the stem isforced down by pressing quickly upon the head 7, and when the stem isre-- leased and the valve closed by the action of the spring, thistrapped water can only escape downward slowly as the valve closes, thuspreventing what is known as water hammer by a sudden closing of thevalve.

-.[-he threaded sleeve held up by the spring is important because afterthe valve is closed,

7 I claim and desire to secure by Letters Patent is- 1. A faucetcomprising a casing, a downwardly diverging valve seat therein, aconical valve seated therein, a stem on which said valve is mounted,threads on said stem a portion of its length, a sleeve reciprocallymounted in thecasing and threaded to receive said stem, meansforpreventing the sleeve from rotating, said sleeve being also capableof being forced down by pressure to allow the valve to be opened bydirect pressure, and a packing ring surrounding the stem above thesleeve.

2. A faucet comprising a casing, a downwardly diverging valve seattherein, a conical valve-seated therein, a stem on which said valve ismounted, threads on said stem a portion of its length, a sleevereciprocally mounted in the casing and threaded to receive said stem,means for preventing the sleeve from rotating, said sleeve being alsocapable of being forced down by pressure to allow the valve to be openedb direct pressure, a packing ring 'surroun ing the stem above thesleeve, and resilient means for normally retaining the sleeve in itsuppermost position. 7 ,1

3. A faucet comprising a casing, a down wardly diverging valve seattherein, a coni-' cal valve seated therein, a stem on which said valveismounted, threads on said stem a portion of its length, a sleevereciprocally intense mounted in the casing and threaded to receive saidstem, means for preventing the sleeve from rotating, said sleeve belngalso capable of being forced down by pressure to valve openingdownwardlyfrom its seat.

against the current flow, and a guided threaded sleeve normally held upby a spring, through which the valve stem is turnable, said sleeve beingalso capable of being forced down by pressure to allow thevalve to beopened by direct pressure,

A water controlling valve comp-rising a valve opening downwardly fromits ,seat against the current flow, a guided threaded sleeve normallyheld up by a spring, through which the valve stem 1s turnable, saidsleeve being also capable of being forced down by pressure to allow thevalve to be opened by direct pressure, and a. -ring or washerapproximately fitting the casing and having an opening around the valvestem to allow a slow passage of water when the valve stem is forced downor up by direct pressure. to prevent sudden closing of the valve.

6. A water controlling valve comprising a valve opening downwardly fromits seat against the current flow, and a guided threaded sleeve normallyheld up by a spring, through which the valve stem is turnable, saidsleeve being, also capable of being forced down by pressure to allow thevalve to be opened by direct pressure, said valve arranged to check theflow of liquid when in its lowermost position.

In testimony whereof I have hereunto set ADONIRAM J. COLLAR.
